Red algae needs more than a rinse. We handle it the right way—here’s how:
- Inspection: We assess where red algae has taken hold and determine the best softwash method.
- Softwash Application: We apply a gentle detergent to dissolve algae without harming paint, render, or tiles.
- Biocide Treatment: Once cleaned, we apply a biocide to eliminate spores and prevent regrowth for up to 36 months.
- Rinse Down: Final rinse leaves your property looking crisp, clean, and algae-free.
